Solliance has achieved world record cell-level conversion efficiency of 13.5% and module-level aperture area conversion efficiency of 12.2% for perovskite-based photovoltaics using industrially-applicable, roll-to-roll (R2R) production processes.

At the end of 2016, Solliance started a project to develop a stable, reproducible and industrial up scaleable process to manufacture CuInGa(Se, S)2 devices using electrochemical deposition, with a cell conversion efficiency above 15%. A record cell with an efficiency of 15.6% was produced only 6 months later, using electrochemical deposition of copper, indium, and gallium. But the only way to create cells using this potential less expensive production technology is with Back-end Interconnect technology.

On August 24, Dmitry Yakovlev, the Director of Solartek, presented the report “Integrated Photovoltaics (BIPV) for the Plus Energy Building and Smart City technologies” at the conference “Modern Energy-Saving Technologies in Megacities” within Days of Moscow at the Expo 2017 in Astana.

Imec, the world-leading research and innovation hub in nanoelectronics, energy and digital technologies, and partner in Solliance today announced that they have improved their 4x4cm² perovskite module achieving a certified conversion efficiency of 12.4%, which is amongst the highest for this size of perovskite modules.
